However, the demise of Facebook Poke will unlikely come as much of a surprise to many, with the app often being viewed as a less than successful Snapchat clone. Described by the social network as a "simple and fun way to say hello to your friends", Poke allowed users to send messages, photos and videos lasting up to 10 seconds, which would disappear after they had been viewed.

The app was released at the same time that Snapchat began to gain traction, and as noted by Mashable, the app promptly disappeared from Apple's "top 25 apps" charts, whereas Snapchat was boasting that users were sending over 700 million messages each day.

For those heartbroken about the closure of Poke, don't worry, you can still "poke" your Facebook friends via the web.

The closure of Facebook Camera unlikely has got many people weeping, either. This app, for those who remember, was essentially a copy of Instagram, which Facebook acquired in 2012 for $1bn. The app, much like Instagram, enabled users to quickly snap, edit and upload images to Facebook, while viewing their friends images using the built-in photo feed.

Such functionality now comes baked into Facebook's standalone iPhone app, so given that, coupled with the rise of Instagram, the demise of Facebook Camera comes as little surprise.
